Foreword
YS/T 124 "carbon products manufacturing Determination and calculation of heat balance of the furnace" is divided into five parts.
--- Part 1. rotary kiln;
--- Part 2. Tank calciner;
--- Part 3. Electrical calciner;
--- Part 4. roaster;
--- Part 5. Graphite resistance furnace.
This section YS/T Part 4 124.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This part is YS/T 124-1994 "carbon products manufacturing Determination and calculation of heat balance of the furnace," in part roaster amendments.
Compared with YS/T 124-1994, the main changes are as follows.
--- Specification standard unit of measurement, symbols and text formatting;
--- Furnace surface heat unified concept, which will help with the actual production site, to facilitate determination;
--- Furnace heat storage increase is calculated starting with the furnace heat storage differ.
The non-ferrous metal part by the National Standardization Technical Committee and centralized.

Carbon products manufacturing furnaces
Determination and calculation of heat balance
Part 4. roaster
1 Scope
YS/T of the provisions of section 124 of the thermal balance determination and calculation method of producing carbon products covered (or open) roaster.
This section applies to the production of carbon products covered (or open) Determination and calculation of heat balance of the roaster, baking graphite electrode products
Burning may also refer to the application.
2 measurement system
Thermal balance determination system, under normal operation conditions, from warm-up to a high temperature baking process in line with the requirements of the curve, preheat the oven chamber to the high
As a system within a measurement cycle between room temperature oven.
3 Determination of requirements and time
3.1 was measured in the time to run the chamber must produce the same product specifications, installed furnace capacity roaster chamber must meet the technical regulations of each
Furnace room temperature to run the process control technology products at or near the firing curve, stable operation and good working conditions.
3.2 Determination of a predetermined time period to run, under normal circumstances, take each time moving a lid, or move a burning aircraft and Unicom
Cover time, time is measured.
3.3 Determination period to within firing qualified products unit mass of heat balance calculation basis.
4 measurement items and methods
4.1 Determination of the amount of material entering the furnace chamber
4.1.1 Determination of mass charged into the furnace chamber carbon products manufacturing blanks.
4.1.2 Determination of mass charged into the furnace chamber filler.
4.1.3 Determination of physical and chemical analysis of materials, including products and green filler temperature, moisture and green products and applications based low filler
(Bits) heat and specific heat.
4.2 Determination of the chamber into the fuel and hot water
4.2.1 heavy oil or gas accumulated amount accumulated amount, determined by the existing production equipment and measurement methods of measurement.
4.2.2 The nature of the physical and chemical analysis of the fuel, including fuel temperature, pressure, composition, and on average lower than the thermal application group (bits) heat.
Wherein. Determination of fuel applications based low (bits) calorific value is calculated by the following formula may be used.
Qmgdwy = 126CO 108H2 359CH4 636C2H6 234H2S (1)
Where. CO; H2; CH4; C2H6, H2S --- chemical composition of the fuel volume fraction (%).
4.2.3 Determination of the cumulative amount of hot water into the oven chamber temperature.
